Hybrid Cache Placement for Physical-Layer Security in Cooperative Networks
IEEE Access, 2018 Due to the broadcast nature of wireless transmission, traditional wireless two-hop relaying is vulnerable for eavesdroppers to overhear messages. In order to enhance the physical-layer security, this paper studies one cooperative network with caching ...

Secure Transmission for Relay Wiretap Channels in the Presence of Spatially Random Eavesdroppers [PDF]
, 2015 We propose a secure transmission scheme for a relay wiretap channel, where a source communicates with a destination via a decode-and-forward relay in the presence of spatially random-distributed eavesdroppers.

Secrecy Outage Probability: Revisited.
CoRR, 2022 This paper technically explores the secrecy rate $Λ$ and a maximisation problem over the concave version of the secrecy outage probability (SOP) as $\mathop{{\rm \mathbb{M}ax}}\limits_{Δ} {\rm \; } \mathbb{P}\mathscr{r} \big( Λ\ge λ\big) $. We do this from a generic viewpoint even though we use a traditional Wyner's wiretap channel for our system model

Secrecy Outage Probability of Network-Coded Cooperative Communication
CoRR, 2014 We evaluate the secrecy performance of a multiple access cooperative network where the destination node is wiretapped by a malicious and passive eavesdropper. We propose the application of the network coding technique as an alternative to increase the secrecy at the destination node, on the top of improving the error performance of the legitimate ...

IET Communications, 2022 This paper investigates the impact of a dual‐signal selection (i.e. selection of direct signal and relay signal) and multiple eavesdroppers on secrecy outage probability in cooperative‐relay systems over Nakagami fading channels.

Rate Splitting in the Presence of Untrusted Users: Outage and Secrecy Outage Performances
IEEE Open Journal of the Communications Society, 2022 In this contribution, a thorough investigation of the performance of rate splitting is conducted in terms of outage and secrecy outage for the simultaneous service to a near user and far user, where the latter attempts to overhear the message of the ...

On Secrecy Outage Probability and Average Secrecy Rate of Large‐Scale Cellular Networks
Wireless Communications and Mobile Computing, 2018 We investigate the secrecy performance in large‐scale cellular networks, where both Base Stations (BSs) and eavesdroppers follow independent and different homogeneous Poisson point processes (PPPs). Based on the distances between the BS and user, the intended user selects the nearest BS as serving BS to transmit the confidential information.

IEEE Access, 2021 In this paper, we investigate secure communication in a hybrid relay (HR)-assisted wireless powered cooperative communication network (WPCCN), where an eavesdropper tries to intercept the data transmitted by a source user and the HR simultaneously.
